标题 一个PHP Whois域名检查函数代码
范文
    以前在做PHP主机域名程序时候用的一个Whois检查代码，用来确定所查询的域名是否被注册，函数囊括了大部分的域名后缀，将根据后缀的不同连接到不同的查询服务器，以前能用，时间关系，我现在暂时没有测试那些查询网址现在是否还能用，若不能用，就需要你自己找资料，看看现在的网址是什么。
    01
    02function whois_query($domain) {
    03 $domain = strtolower(trim($domain));
    04 $domain = preg_replace('/^http:///i','',$domain);
    05 $domain = preg_replace('/^www./i','',$domain);
    06 $domain = explode('/',$domain);
    07 $domain = trim($domain[0]);
    08 // 切割域名
    09 $_domain = explode('.',$domain);
    10 $lst = count($_domain)-1;
    11 $ext = $_domain[$lst];
    12 //定义不同域名后缀所需要连接的查询服务器地址
    13 $servers = array(
    14 "biz" => "whois.neulevel.biz",
    15 "com" => "whois.internic.net",
    16 "us" => "whois.nic.us",

    51 "aero" => "whois.information.aero",
    52 "nl" => "whois.domain-registry.nl"
    53 );
    54 if (!isset($servers[$ext])){
    55 die('Error: 没有找到匹配的服务器!');
    56 }
    57 $nic_server = $servers[$ext];
    58 $output = '';
    59 //连接域名服务器:
    60 if ($conn = fsockopen ($nic_server, 43)) {
    61 fputs($conn, $domain."rn");
    62 while(!feof($conn)) {
    63 $output .= fgets($conn,128);
    64 }
    65 fclose($conn);
    66 }
    67 else { die('Error: 不能连接到： ' . $nic_server . '!'); }
    68 return $output;
    69}
    70?>
    函数调用后，将直接返回结果。
